A bad connection can easily give you more voltage drop, up to 12 V.

I am not advocating that we should have excessively long power wiring but we should solve the real problems.

Fortunately, that wasn't the issue. Their crimps were done well, screws and nuts were tightened down sufficiently on both the breaker, battery and PDP.

Edit: Al beat me to it.
